Yeah, a lot of people have said that you don't need a stabilzer with the Calmini SS, but it is much nicer.
I had the Rancho stablizer, and had the same problem with the shock hitting against the centerlink. What I did was put a metal spacer between the plate and the centerlink. I drilled holes in it so the U-bolts could go through.
It pushed it away maybe 1/4 or an inch and was just enough to clear.
